New Build

I have 3 computers which is the least I’ve ever had in over 20 years because I worked as a MIS manager for 20 years in Silicon Valley. I’m an old man of 71 and I have a AMD 955 which is 7 ½ years old and it’s getting slow and a 4 year old i5 which is OK and a 6 ½ year old laptop which I want to replace with a tablet because I don’t go anywhere but it’s nice to have one better that my Fire tablet. So what would you recommend for a new build? I’m thinking a top of the line i5 so I figure this will be the last computer I will build so I might go with an i7 but I understand for a normal person which I am now you can’t tell the different between an i5 and i7 but I also want an 8th generation. Well I just wanted to vent a little and maybe get some ideas.

Thank you for your input
I am going with Intel
Do Not need 16 GB of Ram
Why would I buy a Hard drive with 5400RPM because I think only laptop come with that
The Video card is way over what 99% of what people need
I have a nice EVA 850 Watt power supply I got for less that $65
Where can I buy a Windows 10 Home OEM 64-bit that is not pirated

I play games and I have 8 GB for RAM which is more that I need to play any game so I just can't see 16 GB's of RAM unless it's for ego
I agree with the Hard Drive but I have been building computer for many years and I never put a 5400 RPM Hard Drive on my computer and for the life of me I would never understand why someone would do that.
I have a R9-270x video card I paid less than $200 and I can't see how my games can play any better
amazon has got many pirated Windows 10 software and that is why I ask
I agree $750 to $800 would be better for me.
Thank You for your input

CPU:AMD - Ryzen 5 2600 3.4GHz 6-Core Processor ($159.89 @ OutletPC)
I did some research and your right about this CPU
We all have different ideas about putting a computer together and it doesn't matter how much you think you know you can always learn.
Thank you for the CPU info, which really help me
